Title: Takashi Asao and His Steam Turbine Sealing Invention.
Introduction
Takashi Asao is an inventor associated with Hitachi, Ltd., in Hitachi, Japan. His work includes a patent for a steam supply system designed to provide gland sealing steam to a steam turbine.
Latest Patents
Asao is credited with 1 patent: “Gland Sealing Steam Supply System for Steam Turbines.” The invention describes a waste heat recovery boiler that generates high-pressure and low-pressure steam from gas turbine exhaust heat. Separate steam extraction and supply arrangements deliver sealing steam to the turbine’s high-pressure and low-pressure gland portions. A pressure regulator manages the high-pressure supply and directs excess steam to a condenser, while a reducing valve provides low-pressure steam at a constant pressure.
Career Highlights
Asao’s patent reflects engineering work focused on steam turbine systems and the use of recovered heat. The described arrangement integrates steam generation, pressure regulation, and gland sealing within a waste heat recovery setup.
Collaborations
Asao’s listed coworkers include Kiyoshi Takeuchi and Yoshiki Noguchi. The available information identifies them as colleagues but does not specify their roles in the patent.
Conclusion
Takashi Asao’s patented system combines waste heat recovery with controlled high- and low-pressure gland sealing steam supplies for steam turbines.
